Server update: Autohost and Ratings

Known issues

• The ladders are missing many players and display unranked players as rank 2147483647. Will be fixed on the next downtime.

Autohosts

• Directly after each battle there is a 35 second discussion time with no polls.
• Afterwards, a map majority vote is called. Vote for one of two maps using Yes/No, the map with the most votes wins after 25 seconds. This will be extended to four maps as soon as the UI has been updated.
• Once the map is selected and if there are more than 6 players a start vote will be called.
• If the game hasn't been started, normal votes can now be called as usual.

Ratings

• Ladder ratings are now chosen such that the rating system is 75% confident that the player has at least that rating.
• Ratings now have higher variance, meaning they will allow for bigger changes between days.
• Ratings will change faster the more games are played.
• Fixed an error in the formula to calculate ratings from team games.
• Rating uncertainty has been replaced by standard deviation. The +- numbers shown represent one standard deviation.

Minor changes and fixes

• Fixed some user flags being incorrect.
• Prevent users from vandalizing empty autohosts by setting custom maps on multiple of them.
• Only count custom matches for Elo if the teams are even.
• Spectate afk players on game start.
• Allow anyone to call !spec to spectate afk players.
• Only allow allies to vote on in-game kicking.
• Abort MM battles if a player doesn't load in and ban that player, use !force to circumvent this.
• Reduce force start time from 180sec to 160sec.
• Fix autohosts getting deleted on every server restart.
• Add the logged in player to the end of the ladder if he isn't on it.
• Add a searchable ladder page with the full ladders.
• Make sure the Space Lobster rank is unreachable.
• Prevent an exploit where players could spoof awards and force start games.
• Fix XP not being given out for some battles.
• Disallow joining matchmaker if the player is still fighting in another battle and that battle has been going on for less than five minutes.

Follow-up fixes

• Make ladder inactivity cutoff configurable and don't show the own rank if the player is unranked.
• Fix some errors with the full, searchable ladders. Introduce a new error with ranks being off by one.
• Refine the streamlined hosts: No map change after battle ends, no polls after exited battle, nicer map votes.
• Replace the small teams invitation pop-up by a less obtrusive poll.
• Refine the chat spam protection to only kick in after multiple spammed messages.
